7 Scanning modes Spiral Scanning Multiple contiguous slices acquired simultaneously with continuous table movement during scans Multiple, bidirectional acquisitions Spiral exposure: Up to 100 seconds Spiral pitch: 0.13 to 1.5 (user-selectable) Axial Scanning Multiple-slice scan with up to 64 contiguous slices acquired simultaneously with incremental table movement between scans Fused modes for reconstructing thick slices from thin slice acquisitions Clinical enhancements Bolus Tracking An automated injection planning technique to monitor actual contrast enhancement and initiate scanning at a predetermined level. Spiral Auto Start (SAS) Spiral Auto Start integrates the injector with the scanner, allowing the technologist to monitor the contrast injection and to start and stop the scan (with the predetermined delay) while in the scan room. Continuous CT (CCT)* This application provides visual guidance for interventional procedures using a foot pedal and a remote monitor. Exposures, taken once per rotation in either single or continuous mode, are limited to a 240 degree axial centered beneath the patient to shield the clinician's hands from direct X-ray exposure. CT Fluoroscopy Package* This application provides near real-time guidance for interventional procedures (up to 8 fps) using a foot pedal and a remote monitor. The Fluoro mode is particularly useful in complicated procedures involving breathing and abdomen motion. Rate Responsive CV Toolkit* Enables cardiac imaging and includes an ECG monitor, Retrospective Tagging, Prospective Gating, the Cardiac Viewer, Heartbeat-CS and CT Reporting. Uses the Philips Adaptive Multicycle Reconstruction to optimize the temporal resolution. Step & Shoot Cardiac* Enables low dose, high quality cardiac CT imaging. This axial prospective ECG-gated acquisition technique achieves full heart coverage with sub-millimeter, isotropic resolution within a short breath-hold. Includes automatic arrhythmia detection and handling. Heartbeat CS Pro* Includes ECG Prospective Gating. The scanner automatically triggers axial multislice scan acquisitions using an ECG signal. Philips patented Beat-to-Beat Variable Delay Algorithm enables accurate and reproducible calcium scoring studies. Jog Scan* Jog Scan provides up to 80mm of imaging area for perfusion studies. The scanner acquires two 40mm volumes of interest by translating the couch back and forth doubling the standard perfusion coverage. Pulmonary Toolkit* Pulmonary Toolkit enables the user to trigger a scan at a particular breath level (axial and/or spiral prospective gating), minimizing artifacts caused by respiratory motion. This allows better chest imaging of patients who cannot hold their breath. Pulmonary Toolkit Oncology* Pulmonary Toolkit Oncology includes the Pulmonary Toolkit features plus Retrospective Spiral (4D CT). This feature results in the ability to generate multiple phases allowing for visualization of motion during the respiratory cycle and delineating a target volume. *Optional 7

9 Dose management Reconstruction DoseWise is a philosophy, a set of principles and practices, focused on lowering radiation dose for patients and staff. Philips focuses on system design optimization, current (ma) optimization and increasing dosage awareness to reduce the cumulative risk of radiation while obtaining high-quality images. DoseRight ACS (Automatic Current Selection) Optimizes the dose for each patient based on the planned scan by suggesting the lowest possible mas settings to maintain constant image quality at low dose throughout the exam. DoseRight D-DOM (Dynamic Dose Modulation) Automatically controls the tube current rotationally, increasing the signal over areas of higher attenuation (lateral) and decreasing signal over area of less attenuation (AP). DoseRight Z-DOM (Longitudinal Dose Modulation) Automatically controls the tube current, adjusting the signal along the length of the scan, increasing the signal over regions of higher attenuation (shoulders, pelvis) and decreasing the signal over regions of less attenuation (neck, legs). Dedicated Pediatric Protocols Developed in collaboration with top children's hospitals, Brilliance age and weight-based infant and pediatric protocols optimize image quality with low dose. Dose Performance Data CTDI vol Measurement Head 11.0 mgy / 100 mas Body 5.6 mgy / 100 mas Using IEC standard phantoms RapidView Reconstruction generates up to 20 images per second using a matrix. Reconstruction Field of View 50 to 500mm continuous 25 to 250mm (Ultra High mode) Image Matrix 512 2, and 1,024 2 Cone Beam Reconstruction Philips patented Cone Beam Reconstruction Algorithm (COBRA) enables true three-dimensional data acquisition and reconstruction in spiral scanning. Adaptive Filtering Adaptive filters reduce pattern noise (streaks) in non-homogenous bodies, improving overall image quality. Adaptive Multicycle Reconstruction (Part of Rate Responsive CV Toolkit*) Image data can be prospectively gated or retrospectively tagged. COBRA automatically delivers the best temporal resolution possible (as low as 53mseconds). Evolving Reconstruction Real-time matrix image reconstruction and display in step with spiral acquisition or off-line. Images can be modified for window width and level, zoom and pan prior to larger matrix reconstruction. At the end of the acquisition, all images are updated with the desired viewing settings. Off-Line Reconstruction Off-Line (batch) background image reconstruction of user-defined groups of raw data files with automatic image storage. * Optional 9

10 Networking The Brilliance CT supports 10/100/1000 Mbps (10/100/1000BaseT) network speeds. For optimal performance, Philips recommends a minimum of 100Mbps network speed (1Gbps preferred) and for the CT network to be segmented from the rest of the hospital network. Archiving The full implementation of the DICOM 3.0 communications protocol in the Brilliance Workspace allows connectivity to DICOM 3.0 compliant scanners, workstations, and printers; supports IHE requirements for DICOM Connectivity. DICOM Brilliance Workspace supports IHE requirements for DICOM connectivity and can work with DICOM 3.0-compliant PACS, scanners, workstations, and printers. It supports IHE requirements for scheduled workflow and other integration profiles as defined in IHE Statement. Brilliance Workspace includes DICOM service classes to communicate with the following modalities: CT MR Nuclear Medicine including PET/CT Computed Radiography Radiography & Fluoroscopy (R&F) Type Hard Drive DVD RAM 1 EOD 1 CD Capacity 292 GB 4.7 GB 9.1 GB 700 MB Images 500, , , Patients 4 1, Either DVD-RAM or EOD is standard, dependent on selected options matrix uncompressed matrix compressed 4 Based on 300 images per study DICOM CD Writer A DICOM CD Writer option stores DICOM images and associated image viewing software on very low cost CD media. Images on these CDs can be viewed and manipulated on PCs meeting the minimum specifications. Ideally suited for individual result storage and referring physician support. Brilliance Workspace includes the following DICOM functionality: Service Class User & Provider (CT, MR, NM, Secondary Capture) DICOM Print DICOM Modality Worklist User Query/Retrieve User and Provider Modality Performed Procedure Step User Storage Commitment User Removable Media Filming This function allows the user to set up and store filming parameters. Pre-stored protocols can be set to include auto-filming. The operator can film immediately after each image, at the end of a series, or film after the end of a study and review images before printing. The operator can also automatically film the study at three different windows and incorporate Combine Images functionality to manage large datasets. Basic monochrome and color DICOM print capability are supported. 10
